(Cl. 13S-26) in so far as the cover cannot be fastened to the inner I end of the lower roof rod section, which are pushed during the collapsing of the umbrella into the upper roof rod section. Accordingly, that part of the cover which is located on top of the outer roof rod members will form folds during the closing of the umbrella; the folds hang over the end of the handle, are easily jammed, if pushed between the roof rods, and greatly impair the exterior view of the umbrella.

-It is the object of the invention to eliminate this disadvantage and to enable a fastening of the cover to the umbrella supporting structure and particularly to the inner end4 of the outer roof rod section, whereby the cover is pulled along during the closing of the umbrella and the formation of folds is prevented.

With this object in view, the invention will now be described in detail and with reference to the accompanying drawing, illustrating several preferred embodiments thereof.

Fig. l2 is a cross sectional view on line XII- XII of Fi 1l. 1 y' its apparent from Figs. l and 2, the umbrella stick con-l sists of three collapsible members 1, 2, 3. The upper member 1 carries the crown 4 and the lower member 3 the handle 5.

' A plurality of roof rods or ribs are jointed to the crown 4; they consist of threecollapsible members or sections 6, 7, 8 having the shape of hollow rails.- Member 6 has the largest diameter or cross section and is fastened to 2,710,619 Patented June 14, 1955 the crown 4. The lateral edges 9, Fig. 5, of the upper section 6 of the roof rods are inwardly bent and the lower end of the median part 7 carries a guide sleeve 11, as shown in Figs. 1 and 3. The hollow outer member 8 of the roof rods is open at one side and so located within the median member 7 that it extends with this open side towards closed side 12, Fig. 4, of the median'member ice 7. The ends of both sections 7, 8 overlap each other on a part of their length. A spring 13, Figs. 3, 7, fastened ,A to the outer member 8 may therefore directly enter with` its catch 14 into an opening 15 of the rear wall of member 7.

A brace 17, Fig. 3, is jointed by means of pivot 16 'tothe inner end face of median roof rod member 7; brace 17 is connected at its one end with the main runner 18, Fig. l. This main runner 18 is in the closed position of the umbrella secured to the umbrella stick through a spring catch 19 and in the opened position through'a spring catch 20. An auxiliary brace 21 is jointed to the main brace 17 and the auxiliary braces 21 are connected with an auxiliary runner 22.

When the umbrella is opened, the auxiliary runner 22 effects the extension and the final positioning of the median roof rod member 7, the outer roof rod member 8 having been previously moved into its operative position by the opening of the umbrella. Therefore, a staying of the median roof rod section 7 by the brace 17 and Athe auxiliary brace 21 is not required during the opening of the umbrella. Consequently, the median roof rod member 7 may be directly pushed into the upper roof rod member 6, when the main runner 18, during the collapsing of the umbrella, is no longer supported by the lower catch 19. The outer end 23, Fig. 3, of the upperroof rod member 6 is hereby pushed over spring catch 14 and enables the sliding-in of the lower roof rod member 8.

The cover 24, shown in dotted lines is fastened to the two ends 2S, 26 of the roof rods, Fig. 3, and in addition thereto to a sleeve 29 (Figs. l and 3) that is carried by the outer roof rod structure 8, at a point between these ends, whereby during the collapsing of the umbrella, folds 27, Fig. 2, are formed at the upper end of the col-l lapsed umbrella cover 24.

In order to enable the pushing-in of member 8 into the upper member 6, during the collapse of the umbrella, the cover 24 is fastened to a bent-up portion 28 of the sleeve 29, Fig. v3; this sleeve may be pushed along the roof rod, by means of a projection 30 entering the outer roof rod member 8, during the collapsing of the roof rods. The sleeve 29 which is provided at the upper end with an expanded edge portion 33, may be pushed over the sloping end 32 of roof rod member 6, Fig. 3, whereas projection 30 slides into a slot 31 of the upper rod member 6, Fig. 6, the slot being formed by an inward bend of the sides of this hollow member. l

The movement of the lower roof rodmember 8 is' limited by projection30 which together with sleeve 29 strikes against sleeve 11, located on the lower end o f median roof rod member 7. i

As apparent from the above, the taking along of the cover 24 is effected by sleeve 29, which is provided at the upper end of the outer roof rod member 8 and displaced by projection 30; during the collapsing of the um#v brella, the projection is simultaneously pushed into a loop member and the same may be 'pushed into slot 31 of the upper rod member 6 during the collapsing of the umbrella.

Also here the brace 17 is connected to a pivot 16; the pivot 16 is mounted on a tongue 35, which latter is attached to thc inner side of the end portion of the median roof rod member 7. A spring 13 provided with a catch 14 is connected to the outer section 8 and is operable to enter an opening in the wall of section 7 in the same manner as described in connection with the rst embodiment of this invention.

As mentioned before, thc cover is connected to loopshaped member 34, which projects from the rear side of roof rod section 8. The connecting member 34 embraces the roof rod on one side only; therefore, connecting members 34 will not collide during the displacement of the roof rod section with the connecting member of an adjacent roof rod section. Since the roof rod sections 6, 7 are open at the inside, the connecting member may slide into the same.

In connection with the embodiment of the invention illustrated in Figs. l1 and l2, the cover connected member consists of a bow 36 which is fastened to the outer portion of roof red section 8; the bow projects from the rear portion of section 8, surrounds one side thereof and has at its end a loop 37 to be fastened to the umbrella cover. If the umbrella is collapsed, the end 38 of the bow slides in the longitudinal slot of the upper roof rod section 6. The movement of the lower roof rod section 8 is limited by bow 36 which impacts against the guide sleeve 39 of the median roof rod section 7, Fig. ll.

With this embodiment of the invention, the rear portion of the lower roof rod section 8, including the connecting member projecting therefrom is directed towards the cover; the other portions of the roof rod section are directed towards the cover with their recessed or open portions.

In the case of both of the last mentioned embodiments of the invention, the spring catch 20 for the upper roof rod section 6 enters a notch of the roof rod section 7; .t

for safety reasons and to increase the stability of the roof rods, the connecting member for the cover is located on the inner end of the elongated outer roof rod section 8.

As mentioned above, the end of roof rod section 6 is inclined to facilitate the entrance of the connecting members 34 and 36 into slot 31, provided in the end of this roof rod section; this slot 31 is produced by the inward bending of the lateral edges of the roof rod sections 6, Figs. 6 and 10.

Since certain changes may be made in the above article and different embodiments of the invention could be made r without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.
